I have an 02 lb7 crew cab short bed. The upgrades it currently has are the k&n cold air intake, banks bighead wastegate actuator, twin cooling fans, and an economy tune with the diablosport predator. I just took a couple 200 mile highway trips, and set the cruise at 72mph. Both times I filled up I did the calculations and I was getting 15.5-16.5mpg? I know for sure I should be getting better than this unloaded. Any ideas on why the MPG is this Low? and any ideas for increasing the mileage?

have you cleaned your maf sensor.you can get the cleaner at any auto parts store b sure and get maf sensor cleaner. tire pressure? Fuel filter? Have you cleaned your air filter lately? my truck seems to get the best fuel mileage on the highest possible HP tune. Just be careful with 4-5 and 5-4 shifts.lots of things to try, good luck.

My old 2001 dmax would get 18-24 on the highway. Only mods were cai, exhaust and edge EZ programmer. It was a 3 position setup I don't know if they carry it any more. I think it was like 30/60/90hp

mpg

I just bought a 2001 crew long bed 4x4 to replace my old 2001 that was totalled in a head on..other guys fault.
I had to drive the "new" one 280 miles to get home. set cruise at 65 but you know with a new truck I had to try it out when passing so i wasn't easy on the pedal and at a couple of stops we let it idle a while; and even with all that I got 17.5 mpg completely stock.
